Since March 10, both LYRA and SWAP provide calibrated data in near-real time. Previously, it was only the case for SWAP, LYRA was only delivering its uncalibrated data, labeled as “level1” products. The calibration process applied to reach “level 2”, involves the correction of dark current and of filter degradation, and converts the data into irradiance units (W/m2).
The way the data are calibrated is decribed in the LYRA analysis manual.
